  • Low-Cost DC Motor Speed Control with CMOS ICs
    Two low-cost CMOS ICs manage a 12 VDC, current-limited speed control circuit for DC brush motors. The circuit design (see Figure 1) uses PWM (pulse width modulation) to chop the effective input voltage to the motor. Use of CMOS devices gives the benefits of low power, minimal heat and improved

  • Electrical Considerations of Fan Cooling
    . The standard fan supplied with the amplifiers is a 12V brushless DC motor fan. Like all switching circuits the brushless motor commutation generates electrical noise. If care is not taken in how the fan is connected to the amplifier circuit some of that electrical noise may appear at the output
